Summary:

In the fourth century B. C. E.,
Aristotle introduced the idea that the mind was a blank slate. On the other
hand, we had Plato’s idea that the human mind was an entity that pre-existed
somewhere in the heavens before it was sent down to Earth.

In the seventeenth century, John
Locke, an English philosopher, brought back the idea of the mind being a “white
paper”. His idea of the tabula rasa was that humans were born with an empty
mind and that knowledge is gained solely by one’s sensory experiences. This
idea emphasized that an individual had the freedom to author his or her own
personality. However, Locke believed that humans were born with some innate
ability to process experience.

Rene Descartes, a French philosopher,
believed that humans were born with some pre-existing ideas. These ideas,
according to him, included knowledge in mathematics and the belief in God.

Continental rationalist Gottfried
Wilhelm Leibniz recognized that there must exist a middle ground between the
two extreme ideas of Locke and Descartes. He believed that although rational
ideas are innate, they must be “activated” by experience.

Nowadays, it has been proven that
most of the brain is preprogrammed to take in, process, and organize sensory
input. These parts then improve their ability to perform their tasks throughout
the person’s life. The only part of the
brain that has been proven to be a “blank slate” is the neo-cortex which is
involved in thought and decision-making.

Analysis:

Even before people had a deep understanding of the brain and
the mind, philosophers like Aristotle and Plato were making predictions on
whether intelligence was something inborn or something gained through
experience.

According to Locke and Aristotle humans were born with an
empty mind and intelligence depended mostly on sensory experiences. On the other
side of the argument were Descartes and Plato who believed that humans were
already born with some type of innate intelligence. Leibniz unified both ideas
to resemble something more like the ideas we have today. He said that the brain
was already preprogrammed but that needed input in order to function.

Questions:How could philosophers like Aristotle and Plato make predictions on whether intelligence was a matter of nature or nurture when they didn't even have an understanding on how the brain worked?
